Perhaps you were thinking of the ATI hybrid?

Giesemann Aurora Hybrid review
Well, I was actually basing my answer on the that they provided in this video (6m:35sec). But maybe this is not correct. I am in Europe and here all 80w T5s (including the ATI) are dimmable.

VJV,
I watched and listened to this video, and perhaps misinterpretation of what Ryan said:
At approximately 6:40, Ryan says:
...."since we're dealing with a 6 foot tank, dimmable just isn't a realistic option”
When he says..... "isn't a realistic option", I do not believe he means the 6 foot is not dimmable.
But I do believe he means the 6 foot "isn't a realistic option" means.... TOO Expensive, ie not realistic at least for their use.
I have asked Bulk Reef Supply about this and if any different will post.
Thanks for the video!
Bob

Giesemann Aurora Hybrid review
No problem. The 6 foot dimmable Matrix unit would be less than half the price of the chosen option. I am sure I did not missinterpretate. What I believe happened was that initially the ballasts in these European dimmable units due to voltage differences could not handle the 80w T5.. also, please watch minute 1.13.

The issue with the Giesemann had nothing to do with being dimmable.
From Zack at Bulk Reef Supply:
"For high-output T-5's, the longest bulb length produced is 60"/5ft. With a focus on the best coverage, this just didn't quite meet our needs on a 72" tank.
Regards,
Zack"
Questions about the Giesemann fixtures:
Q1. Am I correct in that the Giesemann Aurora fixtures use a 220v T5 ballast in both the Europe and US versions?
A1: Only for the Auroras with 80W T5 lamps. All lower wattage T5 ballasts are 120V input.
Q2. AND that the US version is supplied with a setup 110vac>220vac transformer to allow for use in the US?
A2: Yes, but only for Auroras with 80W T5 Lamps.
Q3. That is currently the case AND has been so since the introduction of the Aurora in the US?
A3: For 5ft Auroras yes, some 6ft Auroras have been 120V without transformers. All 4ft and smaller Auroras have always been 120V.
Q4. The 120v are all dimmable? Even the early 6 ft?
A4. Correct, all 120V models are all dimmable, including the 6ft model.
The issue with the 5ft Aurora is that the dimmable 80W T5 ballasts in 120V are single lamp. This causes a problem with space as the 80W ballasts are long and won't fit internally. Therefore, 220V T5 (two lamp) ballasts must be used.
In closing, I hope this answers the question about the Giesemann ability to dim in all fixtures, past and present....they are.
There are some T5 fixtures that are not dimmable and the ATI I mentioned above is one...in the 80w version.

I guess the important thing for those interested is that it works. Having said this,
1: they're answer is a bit bs, to be honest, since they did end up going with 5 foot T5s anyway.
2: from his answer it is clear that some 6ft fixtures (the ones that came with 120w ballasts) did not work because they could not operate more than one T5 (and ALL Auroras always have 2 pairs). Maybe this is why initially it did not work.
FYI, the 80w Matrix ii fixture (T5 only) still doesn't dim in the US version, but it does in the European version (which is the one I have over my 80 inch tank at the moment 8x80w ).
Again, I guess this is a mute point. The important is that right now in the US you can buy a dimmable Aurora of any size. I thought it did not (based on a number of threads and also BRS info) but I stand corrected.
Thanks.

Agreed.........
I am planning on the Aurora or Genesis 72" as these will have the LED cluster at each end of the fixture for excellent coverage even though the T5 bulbs are only 60".
My 96" long 300g will a little shy on each end but with a overflow at one end (peninsula tank) and the LED clusters at each end, it should be just fine.
Just waiting on the Genesis to show for comparison to the Aurora
